Abstract: An information processing apparatus includes a processor configured to: display a representative image representing a document file shared by plural users on a screen of a terminal apparatus of a user, a single representative image being prepared for a single document file; and in a case where another user is viewing or editing the document file, display information indicative of the other user and information indicative of a part of the document file which the other user is viewing or editing while displaying the representative image.

Abstract: A file management system includes at least one processor. The at least one processor is configured to obtain information about a target file, a storage location of a related file relating to the target file, and a viewer, and, when the viewer is allowed to access the storage location of the related file, provide, to the viewer, storage-location information indicating the storage location of the related file, and, when the viewer is not allowed to access the storage location of the related file, provide the related file to the viewer.

Abstract: An information processing apparatus includes a display, a setter, and a synchronization controller. The display displays a first document in a first window and also displays a second document in a second window. The setter sets a synchronization setting between the first and second documents. The synchronization controller executes an operation performed on one of the first and second documents also on the other one of the first and second documents when a synchronization setting is set by the setter, and cancels the synchronization setting when one of the first and second documents is in a first state in which it is not being used and restarts the synchronization setting when the corresponding one of the first and second documents is changed from the first state to a second state in which it is being used.

Abstract: An information processing apparatus includes a processor configured to display, on a display screen of a terminal device used by a user: a shared work region as a common work region that is accessed by plural users and that enables the plural users to execute work in cooperation; and an operation element for the user using the terminal device to input an instruction related to work in the shared work region, in which the processor is configured to display the operation element of a different type according to the user.

Abstract: A document processing apparatus includes a display controller and a button update unit. The display controller performs, in a document processing application that is capable of adding multiple types of objects to an electronic document to be processed, control such that a display screen is displayed, the display screen including multiple recent instruction input buttons that are allocated multiple object adding instructions for adding an object to the electronic document, the multiple object adding instructions having been recently received from a user; and a button update unit that performs button update processing for updating an object adding instruction allocated to one of the multiple recent instruction input buttons to a newly received object adding instruction. In a case where it is determined that object adding instructions for adding a same type of objects to the electronic document to be processed are received consecutively, the button update unit does not perform the button update processing.

Abstract: An information processing apparatus includes at least one processor configured to cause a display to present an interrelationship that represents one or more associations between plural files, the interrelationship being determined in accordance with a history of operation of the plural files performed in a state in which the plural files are presented on the display.

Abstract: An information processing device includes a storage unit, a controller, a storage processor, and a transmitter. When communication with a log management server is unavailable, the controller causes a log of an operation of storing or retrieving data with respect to a storage area on a network to be stored in the storage unit in association with the data. In a case in which the data stored in the storage unit is stored in the storage area and the log associated with the data exists, the storage processor performs a process of storing the log in the storage area in association with the data. In a case in which communication with the log management server is available and a log is stored in association with data in the storage unit, the transmitter transmits the log to the log management server.

Abstract: An information processing apparatus includes: a search part that searches for data that includes information used for searching: a setting part that, in a case where it is not possible to access the information, sets the data that includes the information that cannot be accessed, to be excluded from a search performed by the search part; and a display controller that causes a display part to display the result of the search performed by the search part, and causes the display part to display the data that has been set to be excluded from the search by the setting part.

Abstract: A hydrogen supply passage (12) supplies hydrogen to a fuel cell stack (1) of a fuel cell power plant. Anode effluent discharged from the fuel cell stack (1) is recirculated into the hydrogen supply passage (12) through a recirculation passage (5B ). An ejector (6) provided in the hydrogen supply passage (12) exerts a suction force over the anode effluent in the recirculation passage (5B) depending on a flow velocity of hydrogen supply passage (12). The recirculation passage (5B) comprises a first branch (5C) communicating with the ejector (6) via a recirculation pump (11) and a second branch (5D) directly communicating with the ejector (6). When the suction force of the ejector (6)is not sufficient to promote the recirculation of the anode effluent, the recirculation pump (11) is operated to forcibly recirculate the anode effluent to the hydrogen supply passage (12).

Abstract: A fuel cell system 10 has a fuel cell 16 and a battery 24. An external load 30 is supplied with output power produced by the fuel cell and output power discharged from the battery. The fuel cell system includes a battery charge level monitoring unit 26 which monitors and detects a battery charge level, an accelerator' displacement sensor 32 which detects an accelerator's displacement value and a control unit 11 which calculates demand power to be produced by the fuel cell and varying rate of the displacement value. The control unit corrects the demand power by using a control map having a power correction pattern that is in response to a varying rate of the displacement value and the charge level of the battery.
